An Information Space for Partial Length Perception in Dynamic Touch

Two experiments evaluated change in the perception of an environmental property (object length) in each of 3 perceptual modalities (vision, audition, and haptics) when perceivers were provided with the opportunity to experience the same environmental property by means of an additional perceptual modality (e.g., haptics followed by vision, vision followed by audition, or audition followed by haptics). Experiment 1 found that (a) posttest improvements in perceptual consistency occurred in all 3 perceptual modalities, regardless of whether practice included experience in an additional perceptual modality and (b) posttest improvements in perceptual accuracy occurred in haptics and audition but only when practice included experience in an additional perceptual modality. Experiment 2 found that learning curves in each perceptual modality could be accommodated by a single function in which auditory perceptual learning occurred over short time scales, haptic perceptual learning occurred over middle time scales, and visual perceptual learning occurred over long time scales. Analysis of trial-to-trial variability revealed patterns of long-term correlations in all perceptual modalities regardless of whether practice included experience in an additional perceptual modality.     

Dynamic and Static Balancing Ability of Preschool Children

Performance differences in dynamic and static balance ability of 150 preschool Ss aged 3,4, and 5 yr. were studied. Ss performed 4 balance-beam tasks and 2 balance-board tasks. An Age by Sex (3 × 2) factorial, design employing both univariate and multivariate ANOVA techniques were the statistics used. For both dynamic and static balance Age was highly significant, and the use of multivariate ANOVA indicated significant sex differences on the static balance tasks. The appropriateness of multivariate techniques where more than one dependent variable is measured on the same population was discussed, and the need to take into account the relationship between these variables when analyzing the data was noted.     

Speech Perception in Children With Specific Reading Difficulties (Dyslexia)

Many experimental studies over the last two decades have suggested that groups of children who suffer significant delay in reading also show a weakness in phoneme discrimination and identification. In order to look further at the relation between type of reading deficit, auditory acuity, and speech discrimination, a group of 13 children with specific reading difficulty (SRD), 12 chronological-age controls, and 12 reading-age controls were tested on a battery of speech-perceptual, psychoacoustic, and reading tests. A sub-group of children with Specific Reading Difficulty (SRD) were poor at speech discrimination tests, whereas the rest of the SRD group performed within norms. For this sub-group, discrimination performance was particularly poor for consonant contrasts differing in a single feature that was not acoustically salient, and problems were encountered with nasal and fricative contrasts as well as with stop contrasts. These children did not differ from controls in their performance on non-speech psychoacoustic tasks. An evaluation is made of the reported phonemic awareness skills of beginning readers with regard to speech-processing issues which may help in understanding what factors are important in reading development.

Disjunctive Concept Utilization in Preschool Children

Summary

Twenty-four children, eight each in three age groups, were asked to “play a game” which required them to utilize disjunctive concepts such as “blue or car.” The disjunctive concepts used were the nine which can be formed by combining one value from among three possibilities on the color dimension (green, blue, red) with one value from among three possibilities on the form dimension (car, boat, airplane). The task consisted of 18 five-choice trials with each of the nine disjunctive concepts represented twice—once with the color mentioned first and once with the form mentioned first. Ss were required to pick the positive instance card. All three groups performed significantly better than chance (ps. < .0001) on the task. A significant relation between age and performance on this task was found (Rho = .65, p < .05). There were no sex differences. The results are discussed in relation to task variables and an associative view of cognitive development.     

An Observational Technique for Preschool Children

Summary

A method for direct observational study of early peer-social and objectdirect behavior for human subjects was designed to be articulated with techniques widely used in studies of social behavior in infrahuman primates.

Occurrence of behavior fitting the definitions of each of six categories of object behavior and nine categories of social behavior is noted once during each 15-second interval. The number of recorded intervals in a 15-minute session provides the basic scoring unit.

Observer reliabilities were estimated from paired data and four observers. Thirty-eight Negro and white children ages three through five years were observed in three child play groups. Median reliabilities of .95 (range .63 to .98) and .81 (range .69 to .94) were obtained for object and social behavior categories respectively.     

Implicit Knowledge of Grammatical Gender in Preschool Children

The study aimed at investigating the role of nominal gender in animal categorization in preschoolers. Given the regularities characterizing gender system, at both syntactical and morphological level, Italian language is suitable to address this issue. In three experiments, participants were asked to classify pictures of animals as male or female. Half stimuli had names of feminine gender and half of masculine gender. In Experiment 1, Italian speaking adults and preschoolers classified animals according to the nominal gender. This effect was not found with English speaking participants (Experiment 2) but confirmed with 3-, 4-, and 5-year-old Italian-speaking children (Experiment 3). These results showed an implicit knowledge of grammatical gender in preschoolers, suggesting that semantic processing may be modulated by linguistic information.     

Dyadic Versus Individual Storytelling by Preschool Children

A constructive model of recall and communication (D. Edwards & D. Middleton, 1986) and certain whole-word approaches to learning (C. Pontecorvo & C. Zucchermaglio, 1989) were evaluated in conjunction with an investigation of the benefits of joint storytelling on children's cognitive processes. Preschoolers (N = 36, aged 30-62 months) were prompted to compose a story, working with a classmate (during which they talked together freely and generated a mutual narrative) or individually. Findings revealed that, although dyadically generated stones were longer, containing significantly more words, propositions, and additive conjunctions, stories told by individuals contained proportionally more logically connected statements and greater use of the past tense. Moreover, compared with dyadic stories, individually generated narratives contained fewer alterations of the protagonist.     

Temperament,Family Environment and Anxiety in Preschool Children

This research examines the relationship between behavioural inhibition (BI), family environment (overinvolved and negative parenting, parental anxiety and parent-child attachment) and anxiety in a sample of 202 preschool children. Participants were aged between 3 years 2 months and 4 years 5 months, 101 were male. A thorough methodology was used that incorporated data from multiple observations of behaviour, diagnostic interviews and questionnaire measures. The results showed that children categorised as behaviourally inhibited were significantly more likely to meet criteria for a range of anxiety diagnoses. Furthermore, a wide range of family environment factors, including maternal anxiety, parenting and attachment were significantly associated with BI, with inhibited children more likely to experience adverse family environment factors. No interactions between temperament and family environment were found for child anxiety. However, a significant relationship between current maternal anxiety and child anxiety was found consistently even after controlling for BI. Additionally, there was some evidence of a relationship between maternal negativity and child anxiety, after controlling for BI. The results may suggest that temperament and family environment operate as additive, rather than interactive risk factors for child anxiety. This is discussed in the context of theoretical models of child anxiety and directions for future research.     

Partial Reinforcement in a Bar-Pressing Situation with Preschool Children

Forty fifth- and sixth-grade children were given a list of names which they had prerated for Reinforcement Value in a free recall format. The prediction was made that high self-esteem children will learn their liked names more rapidly than their disliked names, but that low self-esteem children would show the reverse tendency. Although an RV-positive effect is noted in the sample, the expected reversal did not occur. A confounding factor proved to be intelligence, since it was impossible to divorce self-esteem from IQ in the sample investigated. The presentation closes with a discussion of the “logical learning theory” on which RV study is based, and the implications that this theory has for the role of self-induced behavior.     

Anxiety and Threat Perception Abnormalities in Normal Children

The current study examined the relationship between childhood anxiety and threat perception abnormalities. Children (N = 105) were exposed to stories reflecting three types of anxiety: social anxiety, separation anxiety, and generalized anxiety. From children's reactions to the stories, a number of threat perception indices were derived. Children's level of anxiety was assessed by means of questionnaires and a structured diagnostic interview. Results indicated that high levels of anxiety, as measured by questionnaires and interview, were accompanied by a high frequency of threat perception, high ratings of threat, a high frequency of threatening interpretations, high levels of negative feelings and cognitions, and an early detection of threat. Furthermore, results seemed to suggest that threat perception abnormalities were mediated by children's general level of anxiety rather than by levels of specific anxiety symptoms.     

Social Cognitive Predictors of Body Image in Preschool Children

To better understand origins of gender differences in body confidence, the present study examines predictors of body image suggested by Social Cognitive Theory (A. Bandura, 1997): models (from mothers, peers), verbal messages (from mothers, peers, teachers), physiological factors (age, body mass, health status), and experience of competence related to body image (social competence, food competence). Variables were gathered from child interviews, mother questionnaires, and teacher questionnaires for 94 preschool children (52 boys, 42 girls; mean age – 54.2 months; 90.2% Caucasian). Body image was measured with seven same-gender silhouettes (M. E. Collins, 1991). No gender differences were found for the body image of preschool children. Messages from the mother to “be bigger” were the most consistent predictor of body image. However, only for boys were mother's messages a valid reflection of the child's actual body mass, which if continued, could produce greater body confusion for girls at later ages.     

Factors Associated with Transposition Behavior of Preschool Children

To assess ideas, derived from a contextual paradigm, stressing the influence of adolescents' perceptions of the physical and social components of their school environment on their self-esteems and academic performances, 183 black early adolescents (mean age = 12.1 years, SD = .5 years; 54.6% female) were administered five semantic differential scales. The first provided a measure of self-esteem, while the remaining four provided measures of perceptions of the social environment of the school (i.e., of peers and of teachers) and of the physical environment of the school (i.e., of the classroom and of the school building). There were few systematic sex differences in responses to the scales. As predicted, school environment perceptions were significantly related to self-esteem in both males and females. However, although self-esteem and a report of grade point average, as a measure of academic performance, were significantly related, there was no relation between school environmental perceptions and reported grade point average.
